Make your homemade cajun seasoning by combining all the cajun seasoning ingredients together and mixing well.
Make your pasta according to package instructions. If your pasta is done before the rest of the dish, drizzle your fully cooked and drained noodles in a splash of olive oil and set aside.
While your pasta is cooking, make your cajun chicken: In a large skillet heat the olive oil over medium heat and add the chicken breasts. Add a pinch of the homemade cajun seasoning to each chicken breast and then cook for 3-5 minutes. Flip each chicken piece, sprinkle the second side with another pinch of cajun seasoning, and cook another 3-5 minutes or until brown on each side and fully cooked. Remove chicken and set aside on a plate.
In the same skillet that the chicken was cooked in, add the butter and minced garlic until the butter is melted. Add the sliced mushrooms and bell pepper and cook for a few minutes until tender.
Add in the chicken broth, cream, almond flour, parmesan cheese, garlic powder, and pepper and allow to simmer (stirring occasionally) until the sauce starts to slightly thicken, about 5 minutes.
Add in the pasta and stir to coat. Place the chicken breasts on top of the creamy cajun pasta and sprinkle with extra parmesan cheese and chopped fresh parsley. Enjoy!
